PATENT JESSE REYNOLDS, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO A WVILLIAM T. REYNOLDS, OF SAME PLACE.

' WATER-BACK.

' SPECIFICATION forming part of Letters Patent No. 448,995, dated March 24, 1891.

' Application filed November 25,1890. Serial No. 372,633. (No model.)

To all whom it may concern:

Be it known thatI, J EssE REYNOLDS, a citizen of the United States, residing at the city of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Water -Backs, of which the following is a specification.

My invention has relation to certain improvements in the construction and arrangement of a Water-back for ranges and other somewhat similar heating appliances.

The principal objects of my present invention are, first, to provide a water-back especially adapted for use in connection with ranges and one which is comparatively sim: ple in construction and exceedingly effective and durable in action; second, to provide a water-back in which the front or face is partially corrugated in order to permit of expansion and contraction in use without cracks or fractures being formed therein, and, third, to provide a Water-back possessing a maximum surface for quickly and uniformly heating the water circulating therethrough.

The invention consists of awater-back constructed and arranged substantiallyin the manner hereinafter described, and pointed out in the claims.

In the accompanying drawings,formingpart hereof, Figure 1 is an isometrical perspective view of the improved Water-back embodying the characteristic features of my invention. Fig. 2 is a vertical transverse sectional view through the same on the line .90 w of Fig. 3, and Fig. 3 is a horizontal sectional view on the line y y of Fig. 2.

Referring to the drawings for a further description of my invention, Ais a shell or casing of generally rectangular form, made of cast or wrought iron or other suitable material,

7 and provided upon the exterior of the face thereof with channeled ribs A for securing the casing to place in the fire-box of a range or other heating appliance. One portion a of the face is flat or plain surfaced and the other portion a is partially depressed, forming a ribbed or corrugated surface, and which latter surface a in use is exposed to the direct heat of the fire, as Well as the bottom a of the portion a, forming a roof above the corrugated or ribbed surface (L in order that the flame of the fire may lick continually along the ribbed surface a upward in contact with the roof a, imparting a direct intense heat thereto, and then outward, thereby presenting a maximum surface for heating the water circulating through the interior of the water-back. The ribbed or corrugated surface a not only presents a maximum surface to the fire and Water, but also expands when heated and contracts in cooling without cracking or otherwise impairing the same. Moreover, in use the faces, sides, and ends of the shell or casing are constantly exposed at the same time to the heat of the fire and to the cold Water entering continually the Waterback, and consequently the respective Walls of the shell or casing thereof are subjected to very severe internal strain; but the corrugations or ribs a permit the same to expand and contract uniformly, and thus to withstand such strain without injury or deterioration, whereby the durability and usefulness of the same are greatly enhanced.

b is a horizontal partition dividing the interior of the casing or shell A into two compartments and serving to promote the circulation of water therethrough. The partition I) is attached to the back wall of the casing or shell A and to the corrugated or ribbed portion a and extends nearlybut not quite to the respective ends of the shell or casing, so as to form ports Z and Z, Fig. 3, for the passage of the water.

0" is an inlet-orifice formed in the rear wall of the casing A and located beneath the partition b.

'r is an outlet-orifice formed also in the rear wall of the casing A, and located above the partition b.

In practice the casing or shell A is mounted in a range or other similar heating appliance in the usual or in any preferred manner and is secured to place by means of the channeled ribs A. The inlet-orifice r is connected with a suitable supply-pipe and the outlet orifice r is connected with an eductionpipe leading to a boiler or to a distributingpipe. In use the cold water entering the lower compartment by the orifice r impinges upon the under side of the partition 1) andis divided into two portions or streams. These two portions or streams separate, and, flowing through the ports Z and Z, enter the upper compartment, from which the water, having been heated by contact with the corrugated portion (L as well as the other portions of the casing, is drawn oil? through the orifice r for use.

The direction of the circulation of the water through the shell or casing A is clearly indicated by the arrows in the drawings and will be readily understood therefrom.

Having thus described the nature and objects of my invention, What I claim as. new, and desire to secure by Letters Patent, is

1. The herein-described water-back provided with a face having a flat or plain surfaced overhanging portion a and a partiallydepressed portion (R, the construction being such that recesses are formed on both sides or surfaces of the partially-depressed portion beneath the roof a of said overhanging portion, for the purposes set forth.

2. A water-back consisting of a shell or hollow casing provided with an overhanging and corrugated or ribbed face and with an internal partition extending transversely to the sides of the shell or casing and nearly to the end walls thereof, substantially as described.

3. The combination of a shell or casin g having a face provided with an overhanging part and corrugated or ribbed part, an inlet, an outlet, and an internal partition located between the inlet and outlet and connected with the side walls of the shell or easing, substantially as and for the purposes described.

4. Awater-back consisting of arectangular shell or hollow casing having the face thereof provided with extremital ribs and with an overhanging upper portion formed integral with a corrugated or ribbed lower portion,

inlet and outlet openings and an internal partition interposed between the same and secured to the side walls of the shell or casing and extending nearly to the end walls thereof, substantially as described.

In witnesswhereof I have hereunto set my signature in the presence of two subscribing witnesses.

JESSE REYNOLDS.
